gcc/autoconf tools/ package question
 

Have a couple quick questions. Mainaly how packages for instance this one...

firefox-0.8-i686-pc-linux-gnu.tar.gz

was built. I understand that mcpu/march is separate from host/target. Running a ./configure on some source on this computer will most always return.

checking build system type... i686-pc-linux-gnu
checking host system type... i686-pc-linux-gnu

Does this mean this package is a i686 package and this was how the firefox was compiled? Or was firefox compiled with march=i686?

I understand something built with march=i686 wont run on a i386. what about the ./configure I ran above? Will that still run on a i386?

Hopefully these questions dont sound to confusing

thanks
